Compound fertilizer granulator is a kind of granulator for compound fertilizer production, which generally refers to compound fertilizer double roll extrusion granulator, disc granulator or rotary drum granulator.
The characteristics of compound fertilizer granulator are as follows:
1. The particles produced are spherical.
2. Due to the fact that organic particles can be inlaid with each other under a certain force, no binder is needed in granulation.
3. The particles are solid and can be sieved after granulation to reduce the energy consumption of drying.
4. The organic matter after fermentation does not need to be dried, and the moisture content of raw material can be in the range of 20-40%.
Double roller extruding grnaulator
No drying and normal temperature process is adopted for production of twin roll extrusion granulator, which is formed in one time. The equipment has the advantages of less investment, quick effect and good economic benefit. It is suitable for granulation of compound fertilizer, medicine, chemical industry, feed and other raw materials with high granulation rate.
It can produce various concentrations and types of compound fertilizers (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.). In particular, rare earth, potassium fertilizer, ammonium bicarbonate series compound fertilizer granulation.
The pelletizing disk adopts the whole arc structure, and the granulation rate can reach over 93%. The pelletizing plate is equipped with three discharge ports, which is convenient for intermittent production, greatly reduces the labor intensity and improves the labor efficiency. The reducer and motor are driven by flexible belt, which can start smoothly, slow down the impact force and improve the service life of the equipment.
The bottom of the pelletizing plate is reinforced by several radiating steel plates, which are durable and never deformed. Thickened, weighted and solid base design, without anchor bolt fixation, stable operation.
Rotary Drum Granulator
Drum granulator is one of the key equipment in compound fertilizer industry. The drum granulator adopts special rubber plate lining or acid resistant stainless steel lining plate, which realizes automatic scar and tumor removal, and cancels the traditional scraper device.
The machine has the characteristics of high ball forming strength, good appearance quality, corrosion resistance, wear resistance, low energy consumption, long service life and convenient operation and maintenance.
